Isigubhu se-OPC isifinyezo sesigubhu se-organic photoconductive, esiyingxenye ebalulekile yamaphrinta we-laser namakhophi. Lesi sigubhu sinesibopho sokudlulisa isithombe noma umbhalo endaweni yephepha. Izigubhu ze-OPC zivame ukukhiqizwa kusetshenziswa uhla lwezinto ezikhethwe ngokucophelela ukuqina kwazo, ukuqhutshwa kukagesi, kanye ne-photoconductivity. Ukuqonda izinto ezisetshenziswa ezigubhu ze-OPC kunganikeza ukuqonda okubalulekile ekusebenzeni nokuphila isikhathi eside kwalezi zingxenye zephrinta ezibalulekile.
Okokuqala, izigubhu ze-OPC ziqukethe into eyisisekelo eyenza umgogodla wesigubhu. Le substrate ngokuvamile yenziwe ngento engasindi futhi ehlala isikhathi eside njenge-aluminium noma ingxubevange. I-Aluminium iyinketho ethandwayo ngenxa ye-conductivity yayo enhle kakhulu yokushisa, evumela ukuchithwa kokushisa okuphumelelayo ngesikhathi sokuphrinta. I-substrate idinga ukuba namandla ngokwanele ukuze imelane nokuzungezisa njalo kanye nokuxhumana nezinye izingxenye zephrinta ukuze kuqinisekiswe ikhwalithi yokuphrinta engaguquki nokuphila isikhathi eside.
Into yesibili ebalulekile esetshenziswa kuzigubhu ze-OPC ungqimba lwe-organic photoconductive. Lesi sendlalelo sisetshenziswa ngaphezulu kwesigubhu esingaphansi kwe-photosensitive futhi sinesibopho sokuthwebula nokugcina inkokhiso ye-electrostatic edingekayo ukuze kudluliswe isithombe. Izendlalelo ze-organic photo-conductive ngokuvamile zihlanganisa izinhlanganisela eziphilayo ezifana ne-selenium, i-arsenic, ne-tellurium. Lezi zinhlanganisela zinezakhiwo ezinhle kakhulu ze-photoconductive, okusho ukuthi zihambisa ugesi lapho zivezwa ekukhanyeni. Izendlalelo ze-organic photoconductive zakhiwe ngokucophelela ukuze kugcinwe ibhalansi enembile ye-conductivity, ukumelana, nokuzinza, okubalulekile ekukhiqizweni kabusha okunembile kwezithombe nombhalo.
Ukuze kuvikelwe isendlalelo se-organic photoconductive esintekenteke, izigubhu ze-OPC zinento evikelayo. Lokhu kunamathela kuvame ukwenziwa ngongqimba oluncane lwepulasitiki ecacile noma i-resin, njenge-polycarbonate noma i-acrylic. I-coating evikelayo ivikela ungqimba lwezinto eziphilayo ezicini zangaphandle ezingehlisa ukusebenza kwayo, njengothuli, ugesi omile, nokulimala ngokomzimba. Ngaphezu kwalokho, ukunamathela kuvimbela isigubhu se-photosensitive ukuthi sithintane ngqo ne-toner ngesikhathi sokuphrinta, kusiza ukuvimbela ukungcoliswa kwe-toner nokuqinisekisa ikhwalithi yesithombe engaguquki.
Ngokungeziwe kulokho okubalulekile okukhulunywe ngenhla, izigubhu ze-OPC zihlanganisa ezinye izici ezihlukahlukene ukuze zithuthukise ukusebenza kwazo. Isibonelo, isendlalelo sesithiyo se-oxide singangezwa ukuze kuthuthukiswe ukuvikela ungqimba lwe-organic photoconductive kumoya-mpilo, umswakama, nezinye izici zemvelo. Lolu ungqimba ngokuvamile lwenziwa ngefilimu elincanyana le-aluminium noma impahla efanayo futhi lusebenza njengesithiyo esilwa nokuguquguquka. Ngokunciphisa i-oxidation, ukusebenza okuphelele kanye nempilo yesevisi yesigubhu kunganwetshwa kakhulu.
Ukwakheka kwezinto ezisetshenziswa ezigubhu ze-OPC zakhelwe ukuhlinzeka ngekhwalithi yokuphrinta engcono kakhulu, ukuqina, nokuthembeka. Into ngayinye inenjongo ethile, kusukela ku-substrate ehlinzeka ngesakhiwo sesigubhu se-photosensitive kuya kusendlalelo se-organic photoconductive esivalela ukushajwa okumile. Ukwazi okokusebenza okusetshenziselwa izigubhu ze-OPC kuvumela abasebenzisi bephrinta ukuthi benze izinqumo ezinolwazi lapho bekhetha izingxenye ezishintshayo, ukuqinisekisa ukuphila isikhathi eside nokusebenza kahle kwemishini yabo yokunyathelisa.
Manje ngethula izigubhu ze-OPC ezisebenza kahle kakhuluI-Ricoh MPC3003, 4000, kanye ne-6000amamodeli. Zuza ikhwalithi yokuphrinta ephezulu nokuthembeka ngalezi zigubhu ze-OPC eziphambili ezivela ku-Ricoh. Zenzelwe ngqo imodeli ye-MPC3003, 4000, kanye ne-6000. Lezi zigubhu zenziwe ngezinto eziqinile ukuze zimelane nokuphrinta kwevolumu ephezulu, zinikeze ukwethembeka okuhlala isikhathi eside. Irola ye-Ricoh OPC isebenzisa ubuchwepheshe obuthuthukisiwe nomsebenzi, onganikeza umphumela wokuphrinta ocacile, ocacile, nonembayo. Uma ufuna ukuthenga izigubhu ze-OPC, bheka iwebhusayithi yethu (www.copierhonhaitech.com) ukuze ukhethe efanelekayo imodeli yakho.
Kafushane, izinto ezisetshenziswa ezigubhu ze-OPC zibalulekile ekusebenzeni nasekuqineni kwamaphrinta we-laser namakhophi. I-Aluminium noma ama-alloys avame ukusetshenziswa njengezinto eziyisisekelo ngenxa yamandla azo kanye nokuhamba kokushisa. Isendlalelo se-organic photoconductive sakhiwe izinto eziphilayo ezifana ne-selenium, i-arsenic, ne-tellurium, ezicupha futhi zigcine amashaji amile. Ingubo evikelayo, evame ukwenziwa ngepulasitiki ecacile noma ngenhlaka, ivikela ungqimba lwezinto eziphilayo ezithambile ezingxenyeni zangaphandle kanye nokungcoliswa kwethoni. Izakhi ezengeziwe ezifana nokuvikela i-oxide zithuthukisa kakhulu ukusebenza kwesigubhu. Ngokuqonda lezi zinsiza, abasebenzisi bangaqinisekisa ukusebenza kahle nokuphila isikhathi eside kwemishini yabo yokunyathelisa.
